Dehydration results from the loss of a significant volume of bodily fluid, which may include depletion of electrolytes, which are vital saline compounds that regulate a number of bodily processes. There are three main types of dehydration: hypotonic, hypertonic and isotonic. Hypotonic dehydration results from a significant loss of electrolytes, while hypertonic dehydration is the result of a significant loss of water. Isotonic dehydration is the loss of water and electrolytes in equal measure. Treatment aims to replenish bodily fluids and restore the proper balance of water and electrolytes. Dehydration may be caused by excessive sweating and overexertion, severe diarrhea or vomiting, or a failure to take in adequate amounts of water.
